Tropical Cyclone Simon
● Data reliability: ReliableWeather satellites monitored it throughout, so its track and intensity are relatively accurate (Atlantic and E. Pacific since 1966, other basins since 1980).
Simon at 1980-02-21 08:00:00 (BeijingTime) 在South Pacific首次被记录, peak intensity 为Category 4 tropical cyclone , max wind 约 51.4 m/s (1 分钟平均) , minimum central pressure 950 hPa, at 1980-03-03 20:00:00前后结束, total 记录 47 track points (6 h一个) . 曾Landfall或贴近land.
